交貨長(zhǎng)度又稱用戶要求長(zhǎng)度或合同長(zhǎng)度。標(biāo)準(zhǔn)中對(duì)交貨長(zhǎng)度有以下幾種規(guī)定： </p> <p> A、通常長(zhǎng)度（又稱非定尺長(zhǎng)度）：凡長(zhǎng)度在標(biāo)準(zhǔn)規(guī)定的長(zhǎng)度范圍內(nèi)而且無(wú)固定長(zhǎng)度要求的，均稱為通常長(zhǎng)度。例如結(jié)構(gòu)管標(biāo)準(zhǔn)規(guī)定：熱軋（擠壓、擴(kuò)）鋼管3000mm～12000mm；冷拔（軋）鋼管2000mmm～10500mm。 </p> <p> B、定尺長(zhǎng)度：定尺長(zhǎng)度應(yīng)在通常長(zhǎng)度范圍內(nèi)，是合同中要求的某一固定長(zhǎng)度尺寸。但實(shí)際操作中都切出定尺長(zhǎng)度是不大可能的，因此標(biāo)準(zhǔn)中對(duì)定尺長(zhǎng)度規(guī)定了允許的正偏差值。萊蕪不銹鋼管價(jià)格螺旋管也稱螺旋鋼管或螺旋焊管。</p><div

鋼材力學(xué)性能是保證鋼材較終使用性能（機(jī)械性能）的重要指標(biāo)，它取決于鋼的化學(xué)成分和熱處理制度。在鋼管標(biāo)準(zhǔn)中，根據(jù)不同的使用要求，規(guī)定了拉伸性能（抗拉強(qiáng)度、屈服強(qiáng)度或屈服點(diǎn)、伸長(zhǎng)率）以及硬度、韌性指標(biāo)，還有用戶要求的高、低溫性能等。 </p> <p> 抗拉強(qiáng)度（σb） </p> <p> 試樣在拉伸過(guò)程中，在拉斷時(shí)所承受的較大力（Fb），除以試樣原橫截面積（So）所得的應(yīng)力（σ），稱為抗拉強(qiáng)度（σb），單位為N/mm2（MPa）。它表示金屬材料在拉力作用下抵抗破壞的較大能力。 </p><p> 焊接鋼管也稱焊管，是用鋼板或鋼帶經(jīng)過(guò)卷曲成型后焊接制成的鋼管。焊接鋼管生產(chǎn)工藝簡(jiǎn)單，生產(chǎn)效率高，品種規(guī)格多，設(shè)備投資少，但一般強(qiáng)度低于無(wú)縫鋼管。20世紀(jì)30年代以來(lái)，隨著優(yōu)異帶鋼連軋生產(chǎn)的迅速發(fā)展以及焊接和檢驗(yàn)技術(shù)的進(jìn)步，焊縫質(zhì)量不斷提高，焊接鋼管的品種規(guī)格日益增多，并在越來(lái)越多的領(lǐng)域代替了無(wú)縫鋼管。焊接鋼管按焊縫的形式分為直縫焊管和螺旋焊管。 </p> <p> 直縫焊管生產(chǎn)工藝簡(jiǎn)單，生產(chǎn)效率高，成本低，發(fā)展較快。螺旋焊管的強(qiáng)度一般比直縫焊管高，能用較窄的坯料生產(chǎn)管徑較大的焊管，還可以用同樣寬度的坯料生產(chǎn)管徑不同的焊管。但是與相同長(zhǎng)度的直縫管相比，焊縫長(zhǎng)度增加30~100 %，而且生產(chǎn)速度較低。因此，較小口徑的焊管大都采用直縫焊，大口徑焊管則大多采用螺旋焊。 </p> <p> <br /> </p> <p> <br /> 鍍鋅鋼管鍍鋅可增加鋼管的抗腐蝕能力，延長(zhǎng)使用壽命。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

鋼管還是各種常規(guī)武器不可缺少的材料，qiang管、炮筒等都要鋼管來(lái)制造。鋼管按橫截面積形狀的不同可分為圓管和異型管。由于在周長(zhǎng)相等的條件下，圓面積較大，用圓形管可以輸送更多的流體。此外，圓環(huán)截面在承受內(nèi)部或外部徑向壓力時(shí)，受力較均勻，因此，絕大多數(shù)鋼管是圓管。但是，圓管也有一定的局限性，如在受平面彎曲的條件下，圓管就不如方、矩形管抗彎強(qiáng)度大，一些農(nóng)機(jī)具骨架、鋼木家具等就常用方、矩形管。根據(jù)不同用途還需有其他截面形狀的異型鋼管。
